patch 9.0.1709: dynamic build with python 3.12 breaks Commit: https://github.com/vim/vim/commit/e5e4709a6ac02dc2a17bd6e4d02e799269ba5ea9 Author: Zdenek Dohnal <zdohnal@redhat.com> Date: Sun Aug 13 19:37:09 2023 +0200 patch 9.0.1709: dynamic build with python 3.12 breaks Problem: dynamic build with python 3.12 breaks Solution: if_python3.c: Fix building dynamic Python3 interpreter There are new extern global variables defined in python3 development files, which types are within python3 library, so they break dynamic python3 interpret Vim plugin. Since the variables are used in macro `Py_SIZE` which is used in other python3 headers, the dummy variables have to defined before including Python.h. closes: #12660 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Zdenek Dohnal <zdohnal@redhat.com>
